ABSTRACT:
A method and apparatus for processing a call from a credit card telephone paystation reads magnetic encoded data on a credit card and produces a credit card identification signal. The credit card identification signal is identified as valid prior to enabling the telephone call. Call information data is stored at the telephone paystation including the credit card identification signal, the called number, the time and date of the call and the call duration. The stored call data is transmitted at periodic intervals to a central billing computer upon request by the central billing computer.
